[0090] For ease of understanding, some of the contents involved in the embodiments of this application are described below:

[0091] 1. Regarding the reporting of the terminal capability request filter (UE capability request filter).

[0092] After receiving the capability query message from the first access network device, the terminal reports the supported frequency bands, functions, and function groups. If the NR or Evolved Universal Mobile Telecommunications System (UMTS) Terrestrial Radio Access (E-UTRA) network is nr, eutra-nr, or eutra, and the requested terminal (User Equipment, UE) capabilities are requested, the terminal executes the terminal processing flow. The terminal processing flow is executed once for each rat-type requested.

[0093] The terminal processing flow is as follows:

[0094] First, the terminal compiles terminal capabilities based on the terminal capability request filter in the capability query message, and generates terminal capabilities that match the filter.

[0095] The terminal then reports its capabilities, including filtered capabilities. It may also report a mirror filter, which should be the same as the terminal capability request filter in the capability query message sent by the network.

[0096] Optionally, the specific process of the terminal performing terminal capability compilation may refer to related technologies and will not be described in detail here.

[0097] 2. About ignoring filters.

[0098] Currently, the Radio Resource Control (RRC) specification defines processing latency requirements for RRC procedures. These requirements are expressed as the time from receipt of a downlink (DL) RRC message to the time the UE is ready to receive the uplink grant (UL Grant) for the uplink (UL) RRC response message. Among the different RRC procedures, the UE Capabilities Transfer procedure has the longest latency requirement of 80ms, while the simplest RRC Reconfiguration procedure has a latency requirement of 10ms.

[0099] The rationale for this latency requirement stems from the fact that the UE capability transmission process involves "UE capability filtering." Specifically, the UE needs to customize the content of its reported capabilities based on filters notified by the network, such as the list of frequency bands for which the UE is requested to report its capabilities. This process places high demands on the UE's processing power and memory; therefore, a longer processing latency is tolerated.

[0100] The UE capability filtering feature was originally intended to address the growing UE capability size due to carrier aggregation and ensure that the total UE capability size fits within the maximum Packet Data Convergence Protocol (PDCP) Service Data Unit (SDU) size. However, in the case of enhanced reduced capability (eRedCap), assuming that the UE only supports single component carrier (CC) operation, if the UE only reports UE capabilities related to single CC operation, the total UE capability size is much smaller than the maximum PDCP SDU size (9KB). If the UE supports 29 frequency bands, it is 1.6KB. This essentially means that UE capability filtering does not provide much benefit.

[0101] In the current UE capability transmission process, the UE reports capability signaling based on the received capability query, and the UE reports the supportedBandList in the UE capability, which includes all frequency bands that the UE can support.

[0102] During the current UE capability filtering process, the UE compiles "candidate frequency band combinations" based on the capability filtering criteria received from the capability query. The UE capability filter (frequencyBandListFilter) provided in the capability query received by the network is mirrored into the capabilities reported by the UE. The UE filters the frequency band combinations in the supported frequency band combination list (supportedBandCombinationList) based on the mirrored UE capability filter. UE capability filtering may also affect "candidate feature set combinations."

[0103] Therefore, a simple implementation is that the UE simply ignores the UE capability filter and reports all supported (non-CA) band combinations and associated feature sets. It is beneficial to let the network know that the UE has included all supported band combinations and associated feature sets in the UE capabilities so that the network does not re-query the UE capabilities again.

[0104] The simplest mechanism for optional UE capability filters is to allow the UE to change or modify the applyFreqBandListFilter to include all frequency bands supported by the UE in supportedBandList, rather than querying the mirrored band list filter from the capabilities. The network will see that the mirrored capability filter includes all frequency bands supported by the UE (as shown in supportedBandList) and can determine that there is no need to re-query the UE capabilities.

[0105] The terminal capability reporting processing method provided in the embodiment of the present application is described in detail below with reference to some embodiments and their application scenarios in conjunction with the accompanying drawings.

[0106] 2 , an embodiment of the present application provides a method for processing terminal capability reporting. As shown in FIG2 , the method for processing terminal capability reporting includes:

[0107] Step 201: The terminal sends target indication information to the first access network device;

[0108] The target indication information includes at least one of first indication information and second indication information, wherein the first indication information includes any one of the following:

[0109] A first indication, used to indicate at least one of: a target capability reported by the terminal meets a target filter and a mirror filter reported by the terminal meets a target filter;

[0110] a second indication, used to indicate at least one of: a target capability reported by the terminal does not meet the target filter, a mirror filter reported by the terminal does not meet the target filter, the target capability exceeds the target filter, and the mirror filter exceeds the target filter;

[0111] The second indication information includes at least one of the following:

[0112] A third indication is used to indicate whether the terminal supports terminal capability filtering;

[0113] a fourth indication, used to indicate whether the terminal applies a target filter;

[0114] The fifth indication is used to indicate full-feature capability;

[0115] A sixth indication, used to indicate that the target capability reported by the terminal can be used for a cell after the terminal performs cell handover or cell selection reselection;

[0116] The target filter is a capability request filter carried in the capability query message sent by the first access network device.

[0117] In the embodiment of the present application, when the first indication is used to indicate that the target capability reported by the terminal meets the target filter, it can be understood that the target indication information indicates that the reported target capability meets the target filter. In this case, the terminal can report the target capability according to the target filter.

[0118] For example, if the target filter is a filter for a band combination (BC), the BCs supported in the target capability reported by the terminal only include the BCs of the target filter, or the BCs corresponding to the target filter;

[0119] For example, if the target filter is a filter for a frequency band, the bands supported in the target capability reported by the terminal only include the bands of the target filter or the bands corresponding to the target filter;

[0120] For example, if the target filter is a filter for Radio Access Technology (RAT), the RATs supported in the target capability reported by the terminal only include the RAT of the target filter, or the RAT corresponding to the target filter;

[0121] For example, if the target filter is a filter for a feature set, the Feature sets supported in the target capabilities reported by the terminal only include the Feature set of the target filter, or the Feature set corresponding to the target filter.

[0122] Optionally, when the first indication is used to indicate that the mirrored filter reported by the terminal meets the target filter, it can be understood that: the target indication information indicates that the reported mirrored filter meets the target filter, or the target indication information indicates that the reported mirrored filter is the same as the target filter.

[0123] Optionally, the target capability reported by the terminal does not comply with the target filter, which can be understood or replaced by the target capability reported by the terminal being different from the capability generated after filtering by the target filter. In the case where the second indication is used to indicate that the target capability reported by the terminal does not comply with the target filter, it can be understood as: indicating through the target indication information that the reported target capability does not comply with the target filter, or indicating through the target indication information that the target capability reported by the terminal is different from the capability generated after filtering by the target filter. In this case, the terminal does not report the target capability according to the target filter.

[0124] For example, if the target filter is a filter for BC, then the BC supported in the target capability reported by the terminal does not match the BC of the target filter, or the BC corresponding to the target filter;

[0125] For example, if the target filter is a filter for Band, the Band supported in the target capability reported by the terminal does not match the Band of the target filter or the Band corresponding to the target filter;

[0126] For example, the target filter is a filter for RAT, and the RAT supported in the target capability reported by the terminal does not match the RAT of the target filter, or the RAT corresponding to the target filter;

[0127] For example, if the target filter is a filter for a feature set, the feature set supported in the target capability reported by the terminal does not match the feature set of the target filter or the feature set corresponding to the target filter.

[0128] Optionally, the above RAT may include NR, eUtra, Utra, EN-DC and 6G RAT, etc., which is not further limited here.

[0129] Optionally, the phrase "the mirrored filter reported by the terminal does not match the target filter" can be understood or replaced by "the mirrored filter reported by the terminal is different from the target filter." If the second indication is used to indicate that the mirrored filter reported by the terminal does not match the target filter, this can be understood as indicating, through the target indication information, that the reported mirrored filter does not match the target filter, or indicating, through the target indication information, that the mirrored filter reported by the terminal is different from the capability generated after filtering by the target filter.

[0130] Optionally, the target capability exceeding the target filter can be understood or replaced by the target capability exceeding the capability generated after filtering by the target filter (which can also be referred to as the capability of the target filter). That is, the terminal can report the target capability according to the capability exceeding the target filter. The above-mentioned exceeding means that the target capability, in addition to the capability of the target filter, further includes the capability of at least one specific characteristic, and the specific characteristic is other characteristics other than the characteristics corresponding to the capability of the target filter. For example, in some embodiments, in addition to the capability of the target filter, the terminal can further report the capability required by the second access network device.

[0131] Optionally, in a case where the second indication is used to indicate that the mirrored filter exceeds the target filter, the terminal may report the mirrored filter as exceeding the target filter.

[0132] Optionally, in some embodiments, the full-featured capability includes at least one of the following:

[0133] All segments or frequency bands supported by the terminal;

[0134] All frequency band combinations (BC) supported by the terminal;

[0135] All radio access technologies (RATs) supported by the terminal;

[0136] The complete feature set supported by the terminal.

[0137] Optionally, in some embodiments, the full-feature capability is all supported capabilities corresponding to the target feature, and the target feature is the feature corresponding to the target filter. In the embodiment of the present application, when the full-feature capability is indicated, the target capability sent by the terminal is the full-feature capability, and the full-feature capability corresponds to all supported capabilities corresponding to the feature corresponding to the target filter. Specifically, it includes at least one of the following:

[0138] If the target filter corresponds to a frequency band or frequency band, the full feature capability here refers to all bands supported by the terminal;

[0139] If the target filter corresponds to a frequency band or a frequency band combination, the full feature capability here refers to all band combinations supported by the terminal;

[0140] If the target filter corresponds to RAT, the full feature capability here refers to all RATs supported by the terminal;

[0141] If the target filter corresponds to a feature set, the full feature capability here refers to all feature sets supported by the terminal.

[0142] Optionally, the above-mentioned second indication information and the first indication information can be combined to indicate, for example, in some embodiments, the target indication information can be used to indicate that the target capability is a full-featured capability and that the target capability meets the target filter, specifically, the target capability is reported according to the target filter.

[0143] For another example, in some embodiments, the target capability may be indicated by target indication information as a full-featured capability, and the mirror filter complies with the target filter.

[0144] Optionally, with respect to the third indication above, whether terminal capability filtering is supported can be understood or replaced by whether the terminal can report the corresponding terminal capability (i.e., target capability) according to the target filter, or can be understood or replaced by whether the capability filter is supported. The third indication can be specifically indicated explicitly, for example, by using different bit values ​​to indicate whether terminal capability filtering is supported. Assuming that the bit value is 1 (or true) indicates that terminal capability filtering is supported, and the bit value is 0 (or false) indicates that terminal capability filtering is not supported.

[0145] Alternatively, in some embodiments, a bit value of 1 (or true) indicates that terminal capability filtering is not supported, while a bit value of 0 (or false) indicates that terminal capability filtering is supported. This embodiment offers improved backward compatibility, as existing terminals all support terminal capability filtering. However, for newly introduced terminals or newly introduced features, the terminals may not support terminal capability filtering. Therefore, setting this ratio value to 1 or true indicates that terminal capability filtering is not supported. Conversely, it indicates that the terminal supports terminal capability filtering.

[0146] Alternatively, the indication can be implicit. For example, if the information sent by the terminal carries a corresponding indication, or if the information sent by the terminal carries a third indication, it indicates support for terminal capability filtering. If the information sent by the terminal does not carry a corresponding indication, or if the information sent by the terminal does not carry the third indication, it is defaulted to not supporting terminal capability filtering. Alternatively, in some embodiments, if the information sent by the terminal carries a corresponding indication, or if the information sent by the terminal carries a third indication, it indicates not supporting terminal capability filtering. If the information sent by the terminal does not carry a corresponding indication, or if the information sent by the terminal does not carry the third indication, it is defaulted to supporting terminal capability filtering. This embodiment has the advantage of better backward compatibility, as existing terminals all support terminal capability filtering. However, for newly introduced terminals or newly introduced features, the terminal may not support terminal capability filtering. Therefore, carrying this indication or carrying the third indication indicates that terminal capability filtering is not supported. Conversely, it indicates that the terminal supports terminal capability filtering.

[0147] It should be understood that the corresponding indication can be understood as an indication associated with the third indication, such as the first indication or the second indication. The information sent by the terminal can be the target indication information, or a message associated with the target indication information, such as a capability message. For example, in some embodiments, the target indication information indicates whether the terminal supports terminal capability filtering by whether it carries the third indication. If the third indication is carried, it indicates that the terminal does not support terminal capability filtering; if the third indication is not carried, it indicates that the terminal supports terminal capability filtering.

[0148] Optionally, the above-mentioned fourth indication can be indicated through display, for example, by using different bit values ​​to indicate whether the target filter is applied. Assume that the bit value is 1 (or true) to indicate that the target filter has been applied, and the bit value is 0 (or false) to indicate that the target filter has not been applied.

[0149] Alternatively, in some embodiments, a bit value of 1 (or true) indicates that the target filter is not applied, and a bit value of 0 (or false) indicates that the target filter is applied. This embodiment has the advantage of better backward compatibility, because existing terminals all have the target filter applied. However, for newly introduced terminals or newly introduced features, the target filter may not be applied to the terminal. Therefore, setting this ratio value to 1 or true indicates that the target filter is not applied. Conversely, it indicates that the target filter is applied to the terminal.

[0150] Alternatively, the indication may be implicit. For example, if the information sent by the terminal carries a corresponding indication, or if the information sent by the terminal carries a fourth indication, it indicates that the target filter has been applied. If the information sent by the terminal does not carry a corresponding indication, or if the information sent by the terminal does not carry the fourth indication, it is assumed that the target filter has not been applied. Alternatively, in some embodiments, if the information sent by the terminal carries a corresponding indication, or if the information sent by the terminal carries a fourth indication, it indicates that the target filter has not been applied. If the information sent by the terminal does not carry a corresponding indication, or if the information sent by the terminal does not carry the fourth indication, it is assumed that the target filter has been applied. This embodiment has the advantage of better backward compatibility, as existing terminals all have the target filter applied. However, for newly introduced terminals or newly introduced features, the terminal may not be able to apply the target filter. Therefore, carrying this indication or carrying the fourth indication indicates that the target filter has not been applied. Conversely, it indicates that the terminal has applied the target filter.

[0151] It should be understood that the information sent by the terminal may be the target indication information, or a message associated with the target indication information, such as a capability message. For example, in some embodiments, the target indication information indicates whether the terminal applies the target filter by whether it carries the fourth indication. If the fourth indication is carried, it indicates that the terminal does not apply the target filter; if the fourth indication is not carried, it indicates that the terminal has applied the target filter.

[0152] Regarding the aforementioned sixth indication, if the target indication information includes the sixth indication, the terminal can further report the capabilities required by the second access network device in addition to the capabilities of the target filter. In this case, the first access network device can correctly understand the target capabilities reported by the terminal based on the sixth indication. Furthermore, if the terminal moves to the cell corresponding to the second access network device, the terminal does not need to re-report its capabilities, and the second access network device does not need to re-query the terminal's capabilities, thereby reducing signaling overhead.

[0153] It should be noted that the above-mentioned first access network device can be understood as the access network device corresponding to the current service cell of the terminal or the access network device with the receiving target capability, and the above-mentioned second access network device can be understood as other access network devices other than the first access network device, for example, the access network device corresponding to the neighboring area of ​​the terminal.

[0154] In an embodiment of the present application, target indication information is sent to a first access network device through a terminal; wherein the target indication information includes at least one of first indication information and second indication information, wherein the first indication information includes any one of the following: a first indication, indicating that a target capability reported by the terminal meets at least one of a target filter and a mirror filter reported by the terminal meets the target filter; a second indication, indicating that the target capability reported by the terminal does not meet the target filter, the mirror filter reported by the terminal does not meet the target filter, the target capability exceeds the target filter, and the mirror filter exceeds the target filter; wherein the second indication information includes at least one of the following: a third indication, indicating whether the terminal supports terminal capability filtering; a fourth indication, indicating whether the terminal applies the target filter; a fifth indication, indicating full-feature capability; and a sixth indication, indicating that the target capability reported by the terminal can be used for a cell after the terminal performs cell handover or cell selection reselection; wherein the target filter is a capability request filter carried in a capability query message sent by the first access network device. In this way, when the terminal capability is insufficient or the terminal needs to report capabilities other than those required to be reported by the capability inquiry message, the capabilities can be reported according to actual needs. At this time, the first access network device can understand the capabilities reported by the terminal based on the target indication information, thereby ensuring the correctness of the first access network device's understanding of the target capabilities reported by the terminal.

[0155] Optionally, in some embodiments, the method further comprises:

[0156] The terminal receives a capability enquiry message (ie, UE capability enquiry) from the first access network device, where the capability enquiry message carries the target filter (eg, UE-CapabilityRequestFilter);

[0157] The terminal sends a capability message to the first access network device based on the capability query message, where the capability message includes the target capability.

[0158] Optionally, in some embodiments, the target indication information is implicitly indicated by the mirror filter, wherein the target indication information satisfies at least one of the following:

[0159] In a case where the mirrored filter is different from the target filter, the target indication information is used to indicate that the terminal does not support terminal capability filtering, the terminal does not apply the target filter, and the target capability is at least one of the full-featured capabilities;

[0160] In a case where the mirrored filter is the same as the target filter, the target indication information is used to indicate that the terminal supports terminal capability filtering, the terminal has applied the target filter, and the target capability is at least one of the full-featured capabilities.

[0161] It should be understood that in the embodiment of the present application, the capability message needs to include the mirror filter, and the target indication information can be implicitly indicated based on the mirror filter, thereby saving signaling overhead.

[0162] It should be noted that, in some embodiments, the target indication information is associated with target information reported by the terminal, and the target information includes at least one of target capability and image filter.

[0163] Optionally, in some embodiments, the target capability includes at least one of the following:

[0164] First ability or second ability;

[0165] Third ability;

[0166] The first capability includes at least one of the following: a capability that conforms to the target filter; the mirror filter that conforms to the target filter;

[0167] The second capability includes at least one of the following: a capability that does not conform to a target filter; the mirror filter that does not conform to a target filter;

[0168] The third capability includes at least one of the following: a capability exceeding that corresponding to the target filter; a capability corresponding to the mirror filter exceeding that of the target filter; a full-featured capability; and a capability of a cell that can be used by the terminal for cell switching or cell selection reselection.

[0169] In this embodiment of the present application, the specific content of the target capability corresponds to the target indication information, that is, the target capability matches the target indication information. For example, if the target indication information includes a first indication, the target capability corresponds to the first capability. That is, if the target indication information indicates that the target capability reported by the terminal matches the target filter, the target capability corresponds to the capability that matches the target filter. If the target indication information indicates that the mirror filter reported by the terminal matches the target filter, the target capability corresponds to the mirror filter that matches the target filter.

[0170] Optionally, the capability that complies with the target filter may be understood or replaced by the capability that complies with the filter carried in the capability query message, that is, the capability generated according to the target filter.

[0171] Optionally, the mirrored filter that matches the target filter may be understood or replaced by a mirrored filter that matches the filter carried in the capability query message.

[0172] Optionally, the capability that does not conform to the target filter may be understood or replaced by a capability that does not conform to the filter carried in the capability query message, or a capability generated after filtering by a filter different from the filter carried in the capability query message.

[0173] Optionally, the mirrored filter that does not conform to the target filter may be understood or replaced by a mirrored filter that does not conform to the filter carried in the capability query message.

[0174] Optionally, the capability exceeding the target filter refers to the capability corresponding to the capability exceeding the target filter. Further, the capability exceeding the target filter can be understood or replaced by the capability exceeding the corresponding filter carried in the capability query message, or the capability generated after filtering the filter carried in the capability query message.

[0175] Optionally, the capability corresponding to the mirrored filter exceeding the target filter may be understood or replaced by a mirrored filter exceeding the filter carried in the capability query message.

[0176] Optionally, in some embodiments, the target capability may include a combination of at least two of the first capability, the second capability, and the third capability. For example, in some embodiments, the target capability may include full-feature capabilities, and the target capability complies with a target filter. Specifically, the target capability is reported according to the target filter. For example, in some embodiments, the target capability may include full-feature capabilities, and the mirror filter complies with the target filter.

[0177] Optionally, in some embodiments, the target indication information is carried in a target message, and the target message includes at least one of the following:

[0178] A capability message, wherein the capability message is used to report the target capability;

[0179] UE Assistance Information (UAI) message;

[0180] Radio Resource Control (RRC) messages;

[0181] Uplink message during the Random Access Channel (RACH) process.

[0182] Optionally, when the target message includes a capability message, it can be understood that the terminal carries the above target indication information when reporting the capability.

[0183] Optionally, when the target message includes an RRC message, the target indication information may be reported in a connection establishment message, wherein the RRC message may be understood as a UL RRC message.

[0184] Optionally, the uplink message may include at least one of message 1 (msg1), msg3 and msgA, that is, instructing the terminal to report capabilities previously reported to the network or stored in the network during the RACH process, and the specifics may refer to the target capabilities.

[0185] Optionally, in some embodiments, the target filter and the mirror filter are used to filter at least one of the following characteristics:

[0186] supported frequency bands or frequency bands;

[0187] Supported frequency band combinations;

[0188] Supported wireless access technologies;

[0189] Supported feature sets.

[0190] Optionally, in some embodiments, the type of the terminal includes at least one of the following:

[0191] a reduced capacity terminal or an enhanced reduced capacity terminal;

[0192] Internet of Things (IoT) terminals;

[0193] Vehicle to Everything (V2X) terminals;

[0194] Point-to-point (Device to Device, D2D) terminal;

[0195] Non-terrestrial network (NTN) terminal.

[0196] Optionally, in other embodiments, the above-mentioned terminal may also be a common terminal, that is, it may be a 3G terminal, a 4G terminal, a 5G terminal or a 6G terminal, etc.

[0197] Optionally, the above-mentioned IoT terminals may include narrowband Internet of Things (NBIoT) terminals, machine type communication (MTC) terminals, artificial intelligence Internet of Things (AIoT) terminals, etc.

[0198] Optionally, in some embodiments, the target indication information includes the second indication when a preset condition is met, and the preset condition includes at least one of the following:

[0199] The processing capability of the terminal is limited; the cache capability of the terminal is limited; the processing delay of the terminal exceeds a preset threshold; the terminal does not expect to frequently report terminal capabilities; the capabilities supported by the terminal are limited; the frequency bands supported by the terminal are limited; the frequency band combinations supported by the terminal are limited; the types of wireless access technologies supported by the terminal are limited; the feature set supported by the terminal is limited; the terminal has learned the terminal capabilities required by the second access network device.

[0200] In the embodiment of the present application, the processing delay of the terminal exceeding the preset threshold can be understood as the processing delay of the terminal being too large, and the limited capabilities supported by the above-mentioned terminal can be understood as supporting reduced capabilities.

[0201] It should be noted that the above-mentioned limited can be understood as at least one of the following: less, smaller, less than a preset threshold, smaller than a preset threshold, less than an ordinary terminal, and smaller than an ordinary terminal.

[0202] Optionally, in some embodiments, when the terminal has learned the terminal capabilities required by the second access network device, the target capabilities include at least one of the following: capabilities that meet the target filter, terminal capabilities required by the second access network device; full-featured capabilities;

[0203] Alternatively, in a case where the terminal has learned the terminal capabilities required by the second access network device, the target indication information includes the second indication.

[0204] For example, in some embodiments, when the terminal has learned the terminal capabilities required by the second access network device, at least one of the following may be performed:

[0205] Reporting full-feature capabilities and at least one of the second, third, fourth, fifth, and sixth instructions above;

[0206] Report the capabilities that meet the target filter and the terminal capabilities required by the second access network device, and report at least one of the above-mentioned second indication, third indication, fourth indication, fifth indication and sixth indication.

[0207] In other words, when a terminal reports capabilities that do not meet the target filter, it also reports less than full capabilities. In this case, it needs to report this target indication information. For example, if the UE knows the band configuration of neighboring cells, it will only report the bands to be used by its own and neighboring cells, rather than all supported bands (full supported bands). This eliminates the need for the UE to re-report after moving to another cell, and the network does not need to re-query the terminal's capabilities.

[0208] Optionally, in an embodiment of the present application, after the terminal switches to or reselects the cell corresponding to the second access network device, the terminal does not need to report the terminal capabilities. Furthermore, the above terminal capabilities can be transmitted from the core network to the second cell or the second access network device.

[0209] Optionally, in some embodiments, if the target capability reported by the terminal matches the capability of the target filter, or the mirror filter reported by the terminal matches the target filter, and the target capability reported by the terminal is exactly the full-feature capability of the feature corresponding to the target filter (for example, the feature corresponding to the target filter is a band, BC, RAT, or Feature Set, and the reported target capability is that the terminal supports all bands, BC, RAT, or Feature Set), the target indication information includes at least one of the first indication and the fifth indication.

[0210] Furthermore, after the first access network device receives the target capability and target indication information, the terminal knows that the target capability is the terminal's full-feature capability, and the network side also knows that the target capability is the terminal's full-feature capability. After the terminal moves to the second cell corresponding to the second access network device, it does not need to report capabilities.

[0211] Optionally, in some embodiments, since there may be errors in the internal implementation of the terminal or in the reporting, the first access network device may perform a corresponding action based on the content reported by the terminal. For example, if the target indication information does not match the target capability, the first access network device performs the first action;

[0212] When the target indication information matches the target capability, the first access network device performs a second behavior;

[0213] The first behavior includes at least one of the following:

[0214] Determining that the target capability is invalid;

[0215] Determining not to send the target capability to a target device, where the target device includes at least one of a second access network device and a core network device;

[0216] Sending a capability inquiry message to the terminal;

[0217] The second behavior includes at least one of the following:

[0218] Determining that the target capability is effective;

[0219] Sending the target capability to a target device, where the target device includes at least one of a second access network device and a core network device;

[0220] Determine not to resend the capability query message to the terminal.

[0221] In the embodiment of the present application, the mismatch between the target indication information and the target capability can be understood as at least one of the following:

[0222] In the case where the target indication information is used to indicate the first indication, the reported target capability is the second capability;

[0223] When the target indication information is used to indicate the second indication, the reported target capability is the first capability.

[0224] In the case where the target indication information is used to indicate full-feature capability, the reported target capability is non-full-feature capability.

[0225] Optionally, in some implementations, when the target indication information matches the target capability, the second access network device or the cell corresponding to the second access network device considers that the target capability reported by the terminal is valid.

[0226] Optionally, in some embodiments, when the target indication information does not match the target capability, the second access network device or the cell corresponding to the second access network device considers that the target capability reported by the terminal is invalid.

[0227] It should be understood that, in a case where the target indication information does not match the target capability, the first access network device may send a capability inquiry message to the terminal to re-inquire about the capability of the terminal.

[0228] Furthermore, in the case where the target indication information does not match the target capability, if the core network receives the target capability, the core network device will not send the target capability of the terminal to the second access network device.
